The SMCJ33A-TR is a unidirectional TVS (Transient Voltage Suppression) diode manufactured by STMicroelectronics. It is designed for general purpose overvoltage protection, offering a peak pulse power rating of 1500W (1.5kW) under 8/20µs waveform conditions. The device features a reverse standoff voltage of 33V and a clamping voltage of 69.7V, providing protection for sensitive electronic circuits.
With a peak pulse current capability of 143A (8/20µs), the SMCJ33A-TR is suitable for applications requiring robust transient suppression. The component is housed in a surface-mount DO-214AB (SMC) package, enabling compact PCB layouts. It operates over a wide temperature range of -55°C to 150°C (junction temperature), accommodating various environmental conditions.
The diode is RoHS3 compliant, REACH unaffected, and has a moisture sensitivity level of 1 (unlimited). It is intended for general purpose circuit protection and is not recommended for power line protection applications.
